This year states across the US have passed restrictions on per- and polyfluoroalkyl substances (PFASs) in goods ranging from firefighting foams to fabric treatments. In this special Chemical Watch podcast episode on US PFAS product regulations, North America reporter Julia John discusses what these developments mean with Lauren Tamboer from the Washington Department of Ecology's Hazardous Waste and Toxics Reduction programme; Laurie Valeriano, executive director of the NGO Toxic-Free Future; and Katie Skaggs, a partner with law firm Keller and Heckman.
